Could hamsters provide new clues to Alzheimer's?
A study by CEU San Pablo University in Madrid found that when Syrian hamsters hibernate, their brains undergo structural changes that help their neurons survive even during low temperatures.
By Christian Jarrett The famous studies of London’s taxi drivers – showing they have larger hippocampi (the comma-shaped brain structure in the temporal lobes) than controls – have become a staple of undergrad psychology courses and a classic example of how your brain changes according to what you do with it. Many other studies have also implied an association between hippocampal size and navigational ability – for instance, people with Alzheimer’s, who have lost neurons in this brain structure, tend to experience problems finding their way around. For some time, then, an obvious, though tenta...
The agency on Tuesday said in a statement that plasma infusions from young people provide "no proven clinical benefit" against normal aging, Alzheimer's or a host of other diseases.
In conclusion, there is much to explore with post-mortem MRI and histology studies, which can eventually be of high relevance for clinical pra ctice.
This study shows that it seems that mental activity is as important as physical activity to preserve or increase the chances of healthy aging.” Similar studies that have looked at the link between physical or mental activity and dementia have not usually included as long an observation period as the new analysis does. Most of those studies also start with people who were much older and who were potentially already affected by different types of dementia. In her analysis, Najar adjusted for the fact that some of the women in the study might already be experiencing early signs of dementia. She also found that exercise ...
DEMENTIA is becoming more and more common as people are living longer. There are a number of things which can increase the risk of developing vascular dementia or Alzheimer ’s disease, but how do you know if you’re at risk?
A new study from the University of Gothenburg in Sweden found women with high levels of mental activities - like going to concerts - were 46 percent less likely to develop Alzheimer's disease.
(MedPage Today) -- Engaging in mental or physical activities dropped dementia risk 44 years later
“If the drug proves effective it could give patients a way to manage or lessen their symptoms even if a cure remains out of reach, " said Howard Feldman, M.D., renowned neurologist and director of the Alzheimer's Disease Cooperative Study (ADCS).
In this study, we adopted the chronic unpredictable mild stress (CUMS)-induced mouse model of depression, and then explore antidepressant-like effects and possible molecular mechanisms.Key findingsWe found that BA significantly increased sucrose consumption in sucrose preference test, the number of crossing in open filed test and attenuated immobility time in tail suspension test. Additionally, BA administration notably promoted neuronal differentiation and the number of DCX+ cells. Moreover, BA facilitated immature neurons develop into mature neurons and their survival. FOXG1, a transcription factor gene, which is crucial...
